Embodiment

Below in conjunction with embodiment, the utility model is further elaborated.

As shown in the figure: a kind of torch burning pollutant emission detection system, this system comprises aircraft and pick-up unit 6, pick-up unit 6 is installed on board the aircraft, aircraft is provided with the The Cloud Terrace 5 for controlling pick-up unit 6 switch and flies to control device 7, described aircraft is by ground control station straighforward operation, ground control station comprises the vehicle teleoperation platform for controlling flight path and the The Cloud Terrace straighforward operation platform for controlling pick-up unit, fly the control flight control modules of device 7 to dock with the GCS of ground control station, the landing automatically of flight control modules setting GPS longitude and latitude fixed point, the flight path of aircraft controls on the spherical of distance torch torch head 100m, described aircraft is rotor wing unmanned aerial vehicle,

A kind of method utilizing systems axiol-ogy torch burning described above pollutant emission, the method adopts rotor wing unmanned aerial vehicle to carry pick-up unit, the sphere at distance torch torch head 100m place detects torch burning pollutant emission, is drawn the total emission volumn of unit interval burning pollutant by formula:

Wherein A is ball surface; E is the value of the burning pollutant at sphere bin dA place; R is the radius of a ball; ε is polar angle; η is position angle; Then testing result is revised:

Wherein φ _realfor the total amount of burning pollutant; φ is the detected value of burning pollutant; K is correction factor.

Rotor wing unmanned aerial vehicle carries pick-up unit and detects torch, and pick-up unit comprises kampometer, VOCs detector and H ₂s detector, by flight control modules establishment flight control program, the landing automatically of setting gps longitude and latitude fixed point, flight path controls in the spherical apart from flare tip 100m, rotor wing unmanned aerial vehicle overlaps independently Sensor monitoring by two in flight course, when rotor wing unmanned aerial vehicle departs from setting flight track, ground control station is by manual operation control desk correction unmanned plane track, the two straighforward operation platform of ground control station, i.e. vehicle teleoperation platform and The Cloud Terrace straighforward operation platform, when rotor wing unmanned aerial vehicle arrives assigned address, ground control station sends instruction unpack The Cloud Terrace data acquisition switch, VOCs pick-up unit is started working, by the signal storage collected on the storer of VOCs detector, after rotor wing unmanned aerial vehicle landing, the VOCs information collected is processed,

Or rotor wing unmanned aerial vehicle carries gas sampling instrument, sampling in the position flying to distance flare tip 100m, carries out VOCs Concentration Testing after returning to ground to adopted sample;

Data processing scheme: the data of arrived VOCs, draws the total emission volumn of unit interval burning pollutant by formula:

Wherein A is ball surface; E is the value of the burning pollutant at sphere bin dA place; R is the radius of a ball; ε is polar angle; η is position angle;

Adopt summation to replace integration during actual computation, in this case, formula below can be adopted to calculate:

Then testing result is revised:

Specifically when measuring torch, first adjustment is rocked to rotor wing unmanned aerial vehicle, guarantee rotor 1, frame 2, balance installed by electrical air pump 4, by vibrations coefficient during hovering flight, rock coefficient and drop to less than 10, the symmetry of Multi-axis aircraft has extremely important impact to flight stability, first that flight control modules program setting is good, flight module adopts X4V2 flight module, flight control modules needs the GCS connecting ground control station, flight control modules com port turns serial port connecting wire by USB and is connected to PC, open PC land station just to control rotor wing unmanned aerial vehicle, rotor wing unmanned aerial vehicle straighforward operation platform is provided with six sections of gauge tap, manually increase surely respectively, function shelves, GPS pattern, automatic hovering, self-navigation and landing of making a return voyage, then controlling rotor wing unmanned aerial vehicle flies in torch flame certain distance, torch flame is diversion, VOCs detector is contained on The Cloud Terrace, The Cloud Terrace can carry out switch control rule to VOCs detector, The Cloud Terrace is also equipped with data storage device simultaneously, being connected by steel wire traction line 8 between torch steelframe and rotor wing unmanned aerial vehicle, unmanned plane can being made can not to fall when breaking down on fire.

Flight path controls in footprint as shown in Figure 3, polar angle in the sampling of unmanned plane during flying track and position angle step size controlling less, the value of VOCs is measured more accurate, in order to obtain accurate measurement result, gets little step-length in the region that VOCs concentration value changes greatly, and changing less region, gets larger step-length.

After flight path and step size controlling set, start to sample, the concentration of arithmetic average as the VOCs of this position of three samplings will be carried out in same position.

Error analysis and data processing, first to data analysis, remove the point that measuring error is larger, carry out by method mentioned above the discharge value calculating VOCs, measured value is subject to temperature, wind speed, humidity, the impact of the error of surveying instrument etc. itself, revises calculated value with correction factor k, finally draws the VOCs discharge value of torch.
